Nikon Responds to "Rough" 70-200mm f2.8 VRII Internals

Nikon has posted an official response to customer inquiries about a "rough textured" internal element visible from the front of the lens.

The AF-S NIKKOR 70-200mm f/2.8G ED VR II lens features a component in the lens design which may appear to have surface irregularities or a rough texture when viewed through the front lens element. This rough surface appears in a very small confined area within the lens barrel and is caused by air holes remaining in the metal portion of the lens during component construction. Due to the magnifying effect of the front element this rough surface will appear greatly enlarged when viewed through the front of the lens.

This component’s function is to reduce and remove internal reflections and this textured surface will have no effect on the lenses performance or operation. Nikon would like to assure customers that the lenses optical performance remains unchanged and that this component will not release any dust or particles into the lens itself.
